The Stellar Development Foundation (SDF) announced earlier this week that it burned 55 billion of its Stellar Lumens tokens (XLM), reducing the number of XLM in existence by about 50%.

On Wednesday, a major U.S. cryptocurrency exchange announced staking rewards, estimated at 5% annually, for eligible customers holding Tezos on the exchange.
